Diagnose what's tripping your VFDs. Quantify what's killing your batches.
Voltage sags trip drives. Harmonics overheat motors. Flicker fails GMP audits. Imbalance starves three-phase loads. A power quality study isolates which one is your problem, quantifies severity per IEEE 519 and IEC 61000, and engineers the mitigation · all signed off by a Chartered Engineer.
When a batch fails or a line stops, the operator blames the drive. The drive vendor blames the controls. The controls vendor blames the protection settings. Everyone is right · because none of them has measured the supply. A power quality study installs class-A IEC 61000-4-30 instrumentation at the right buses for the right duration, captures the full spectrum of voltage and current anomalies, and tells you exactly which phenomenon is causing the failure · harmonics, sag, swell, flicker, imbalance, or transient. From there the mitigation is engineering · active filters, line reactors, dynamic voltage restorers, sag conditioners, or upstream contracts with the utility. Until you measure, every fix is a guess.

Twelve years across the power generation value chain. Thermal, hydro, solar, wind, transmission. Grid code compliance to IEEE 1547 and country-specific grid codes. Substation automation to IEC 61850. NERC CIP cybersecurity. Five engineering practices integrated under one stack.
Power generation operators face six structural pain points: grid code compliance under tightening regulator standards, fault ride-through for renewables, aging substation infrastructure, IEC 61850 migration from legacy protocols, NERC CIP and grid-code cybersecurity, and outage window optimisation during maintenance cycles. Most engineering firms specialise in one or two. We engineer to all six under one stack.
Country and ISO grid codes tighten every 2 to 3 years. Fault ride-through envelopes, reactive power capability, frequency response specifications all evolve. Interconnection refusal is the failure mode.
Grid CodeInverter-based resources (solar, wind, battery) must demonstrate FRT compliance across mandated voltage and time envelopes. PSCAD and DigSILENT simulation is the only path to interconnection approval.
FRT · LVRTSubstations commissioned in the 1970s and 1980s carry legacy protection schemes, DNP3 or Modbus communications, and incomplete documentation. Modernisation requires rebuilding the as-built reality first.
BrownfieldModern substations are built to IEC 61850 by default. Legacy substations operate on DNP3, Modbus, or hardwired schemes. Migration projects need IEC 61850 architecture, GOOSE configuration, and testing.
IEC 61850North American bulk electric system operators are mandated to NERC CIP. Other markets are adopting equivalent frameworks. Substation network design must satisfy critical asset identification, electronic security perimeters, and incident response.
NERC CIPEvery hour of unplanned outage hits revenue and regulator scrutiny. Pre-outage engineering through LiDAR, modelling, and simulation moves complexity off the critical path so the live outage contains only assembly.
Outage RiskThe five VB Engineering practices each become a power-generation-specific delivery in this industry. Power studies absorb the grid code and FRT context. LiDAR captures live switchyards safely. As-built engineering rebuilds protection schematics and SLDs. Lean simulation optimises plant availability and outage windows. Risk and safety closes out HAZOP, SIL, and NERC CIP cybersecurity.

OpenCountry-specific technical and operational requirements that any generator or transmission asset must satisfy to connect to the grid. Covers voltage and frequency operating ranges, reactive power capability, fault ride-through envelopes, harmonic emission limits, and protection settings. Failure to demonstrate compliance results in interconnection refusal.
The capability of a generator to remain connected to the grid during voltage dips caused by faults. Grid codes mandate FRT envelopes specifying how long a generator must stay connected at what voltage level. FRT is especially critical for inverter-based renewables. PSCAD and DigSILENT simulation is the primary verification method.
International standard for communication networks and systems in substations. Defines GOOSE messaging for fast protection signalling, sampled values for instrument data, and configuration languages (SCL, ICD, CID, SCD). Modern substations are built to IEC 61850. Brownfield migration from legacy protocols is a frequent engagement.
The power generation engineering scope in 2026 is shaped by three converging forces: the renewables transition pushing inverter-based generation onto grids designed for synchronous machines, the cybersecurity tightening under NERC CIP and equivalent frameworks, and the digital-substation transition from legacy DNP3/Modbus to IEC 61850 across both brownfield retrofits and new builds. An engineering partner that addresses all three in one stack reduces vendor count and integration risk. That is the value proposition under every engagement we run.
Grids built for synchronous machines are absorbing more inverter-based resources. The fault contribution profile, the inertia profile, the frequency response profile all change. Every new solar farm, wind farm, and battery storage project needs a grid code compliance study before interconnection approval.
Inverter-BasedNERC CIP enforcement in North America, the EU NIS2 directive, and equivalent frameworks in India and Australia push substation network design toward stricter electronic security perimeters. Critical asset identification, incident response plans, and regular vulnerability assessments are now table-stakes engineering deliverables.
NERC CIP · NIS2Legacy substations on DNP3 or Modbus protocols are being migrated to IEC 61850. The transition needs system architecture design, GOOSE configuration, sampled values implementation, and rigorous testing. Brownfield migrations are more common than greenfield builds across the next decade.
IEC 61850 Migration800 MW supercritical thermal plant required protection coordination refresh and IEC 61850 migration from legacy DNP3. Load flow, short circuit, harmonics, and protection coordination delivered as an integrated package.
Utility-scale solar farm required full grid code compliance package for interconnection. Fault ride-through verification via PSCAD. Reactive power capability and harmonic emission studies for utility submission.
Aging 220 kV transmission substation needed full as-built reconstruction and NERC CIP-equivalent cybersecurity gap analysis. LiDAR scan completed during live operations. Network architecture audited against the operator's cybersecurity framework.
